输尿管导管顺行灌洗配合输尿管镜碎石的临床观察

Clinical effects of combined ureteroscopic lithotripsy and ureteral catheter irrigation in treating ureteral calculus

目的探讨利用旁置输尿管导管持续顺行灌洗配合输尿管镜碎石术治疗输尿管结石的临床效果。方法2010年6月至2012年6月郑州翅学第一附属医院收治的252例输尿管中下段结石患者在输尿管镜碎石术前先将F4输尿管导管插至结石上方留置，持续注水灌洗的同时进行碎石。结果本研究252例输尿管结石患者中250例成功碎石，碎石成功率为99．2％，平均手术时间25min，术中无输尿管穿孔、撕裂等并发症。结论旁置输尿管导管持续顺行灌洗配合榆尿管镜碎石术治疗输尿管中下段结石，手术视野更清晰，结石不易上移，疗效安全确切。

Objective To investigate the clinical effects of ureteroscopic lithotripsy combined with ureteral catheter irrigation in treating ureteral calculus. Methods Two hundred and fifty-two pa- tients With ureteral calculus from June 2010 to June 2012 underwent ureteroscopic lithotripsy after the placement of F4 ureteral catheter into the ureter. Results Of the 252 patients, 250 cases were treated successfully, the success rate was 99.2%, and the average operations tin4e was 15 to 65 min. No serious complication occurred. Conclusions Ureteroscopic lithotripsy with ureteral catheter irrigation leads to better visibility of the surgical field, prevents the calculus from moving upward, has the advantages of lit- tle injury, good clinical effect, less complication.
